This book contains various articles for hypnotherapists covering practical issues such as helping clients with IBS and fibromyalgia, and information about how clients can make changes to their lives and overcome any fear ever. And there are more theoretical issues such as working with groups and some ideas from positive psychology, as well as what we can learn from the Sufis. The articles assume a model of the brain in which core activities are handled by the 'reptilian' brain, more protective functions (such as fighting, fleeing, feeding, and reproductive behaviour) are handled by the primitive emotional brain, and higher functions are handled by the intellectual brain. In terms of physical parts of the brain, these three areas more-or-less match up to the brain stem and cerebellum, the limbic system, and the cerebral cortex. It also assumes that the primitive emotional brain is very fast and the intellectual brain is much slower and tends to be used less.
